Unless there's some kind of funny issues on your machine, if you right click on the image and select "Save image as..." that should bring up a window that lets you put it somewhere on your disk.
TrueCreation said that there were elements on different layers, such as the text, which is rotated in the version used here, and which may need to be relocated for the other text elements and fitting the page requirements.
Message 28 TrueCreation: I've just searched through my old HD backup and I found the original fireworks png files for the logo from 2002. The canvas is 800x225, so is much bigger than the image on the evc website. It is also layered with the alpha transparencies preserved, so someone can fiddle around with it easily. If someone wants to PM me an email address or tell me where I can upload it i'd be happy to.
For instance the text I have added in the image on Message 23 and Message 27 are on different layers than the logo picture and they are all layered over a cropped version of the Hubble picture on the home page, so I can move them around and resize them.
For instance I could move the "understanding through discussion" in the first image above the "EvC Forum" text.
